The bottleneck is due to the 95th percentile way of billing and the fact big content provider don't buy the bandwidth equally for everyone. Normally you peer (free exchange), if and only if you have almost as much in as out. If you have clearly more input coming to your AS than output, you are supposed to buy your internet transit, else your behaviour is parasitic.

Yes google buys internet transit, but not in Europa, they expect the users to pay for their free services when they are not north american, and they provide the "free VoIP" services this way.

Google, amazon are the problems, they don't assume the cost of their services and make it stand inequally amongst the users. Google is killing the cost model of ISP.

In this condition, how do you expect a sustainable free internet if you destroy the business model of ISP ?

gosh, I made some mistakes on peering. but it does not change the big picture. Sorry.

Peering is just opened to anyone, and people prefer peering to buying. So people prefer to have the less possible amount of traffic leaving their AS.

They peer quite a lot even in Europa, it is a good move when you want to become an ISP.

Still they consider it is the ISP to support most of the cost of the dimensioning of the pipes. Without returned value.

Pfiou, good idea to double check.
